This application is a continuation of U.S. Patent Application Ser. No. 11/636,369, filed on Dec. 8, 2006, now U.S. Pat. No. 7,497,378 entitled “ANTI-TAMPERING PROTECTION FOR MAGNETIC STRIPE READER”, the contents of which are incorporated by reference.
The present invention relates to magnetic card readers generally and to devices, such as point of sale devices, employing magnetic card readers.
Magnetic card readers are employed widely in various applications, including point of sale devices, including, for example, POS terminals, electronic cash registers and ATMs. Traditionally, there has been a concern with data security of such devices. The following patent publications represent the current state of the art: U.S. Pat. No. 6,853,093 and Published PCT Application No. WO 2005/086546 of the present assignee and U.S. Pat. Nos. 5,998,858; 5,861,662 and 6,917,299.
The present invention seeks to provide highly secure magnetic card readers and highly secure point of sale devices including such magnetic card readers.
There is thus provided in accordance with a preferred embodiment of the present invention a magnetic stripe reading device including a magnetic head assembly including a mounting element, at least one information reading sensor having output contacts, the sensor being mounted in the mounting element and a flat cable coupled to the output contacts of the at least one information reading sensor, a portion of the flat cable being arranged in a doubled-over configuration over the output contacts, thereby to provide anti-tampering protection to the output contacts.
There is also provided in accordance with another preferred embodiment of the present invention a point-of-sale device including a housing defining a keypad array location at which an array of keys are located and a display location at which a display is located, a magnetic card reader assembly associated with the housing and including a slot and magnetic stripe reading device, the magnetic stripe reading device including a magnetic head assembly including a mounting element, at least one information reading sensor having output contacts, the sensor being mounted in the mounting element and a flat cable coupled to the output contacts of the at least one information reading sensor, a portion of the flat cable being arranged in a doubled-over configuration over the output contacts, thereby to provide anti-tampering protection to the output contacts.
Preferably, the mounting element defines a peripheral anti-tampering enclosure and the at least one information reading sensor and the portion of the flat cable arranged in a doubled-over configuration are located within the peripheral anti-tampering enclosure. Additionally or alternatively, the flat cable includes multiple conductors arranged generally in a conductor plane and at least one protective wire grid arranged in a plane parallel to the conductor plane.
Preferably, the magnetic stripe reading device also includes a magnetic head assembly tamper detection and disabling circuit which is coupled to the at least one protective wire grid. Additionally or alternatively, the magnetic stripe reading-device also includes a magnetic head assembly tamper detection and disabling circuit which is coupled to at least one of the multiple conductors.
Preferably, the at least one protective wire grid includes a plurality of wire grids arranged in at least two planes disposed on both sides of the conductor plane.
Preferably, the flat cable includes multiple conductors arranged generally in a conductor plane and at least one protective wire grid arranged in a plane parallel to the conductor plane. Additionally, a layer of epoxy is formed over the portion of the flat cable arranged in a doubled-over configuration over the output contacts within the enclosure. Alternatively, a layer of epoxy is formed over the portion of the flat cable arranged in a doubled-over configuration over the output contacts.
There is further provided in accordance with yet another preferred embodiment of the present invention a method of manufacturing a magnetic head assembly including mounting at least one information reading sensor having output contacts in a mounting element and coupling a flat cable to the output contacts of the at least one information reading sensor and doubling-over a portion of the flat cable over the output contacts, thereby to provide anti-tampering protection to the output contacts.
Preferably, the mounting element defines a peripheral anti-tampering enclosure and the at least one information reading sensor and the portion of the flat cable are arranged in a doubled-over configuration within the peripheral anti-tampering enclosure.
The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawings in which:
Reference is now made to
As seen in
A printer (not shown) is disposed within printer housing portion 106 and cooperates with a roll of paper (not shown), which is supported on a paper roll holder (not shown) located within printer housing portion 106. Printed receipts 138 are output via a printer paper slot 140 defined between an edge 142 of top portion 104 and a corresponding edge 144 of a paper roll cover 146.
Reference is now made additionally to
Mounting element 202 is preferably formed of metal and preferably defines a peripheral enclosure 210 having an end slot 212 and two bifurcated side slots 214, each defining a ground contact 216. Extending axially sideways from the peripheral enclosure 210 are two winged, generally planar, somewhat flexible mounting portions 218 having mounting apertures 220 formed therein.
An information reading sensor 230, preferably a magnetic stripe reading sensor, such as an Apollo AP-3350B or AP-2250B, commercially available from Apollo (Zhuhai) Electronics Co., Ltd. Apollo Building, Lanpu Industrial Area E, Jiuzhou Road, Zhuhai, China 519070, is mounted within peripheral enclosure 210, such that a reading surface 232 of the sensor 230 extends outside of the enclosure 210 and the back 234 of the sensor, having electrical contacts 236 thereon, lies within the enclosure 210. Reading surface 232 includes one or more sensing regions 238 connected to contacts 236.
In accordance with a preferred embodiment of the present invention, a flat cable and connector assembly 240 is provided having a plurality of conductors 242 disposed in a conductor plane 244 and preferably having a pair of protective wire grids 246 and 248 disposed in respective planes 256 and 258 located on respective opposite sides of the conductor plane 244. The flat cable and connector assembly 240 includes a connector portion 260 preferably including plural plated-through contact apertures 262 for electrical connection to respective ones of contacts 236 and a pair of plated-through ground contact apertures 264 for electrical connection to respective ground contacts 216.
The connector portion 260 is electrically connected to electrical contacts 236, which extend through apertures 262, preferably by soldering, thereby establishing an electrical connection between the sensor 230 and at least some of conductors 242. Others of conductors 242, designated by reference numerals 266, are preferably coupled to ground by being soldered to respective ground contacts 216.
It is a particular feature of the present invention that, as seen in
In accordance with a preferred embodiment of the present invention, as seen in
Additionally, in accordance with a preferred embodiment of the present invention, protective wire grid 248 extends outwardly from doubled-over portion 270 and is coupled to tamper detection and disabling circuitry 280, preferably located within a protected region 282, of the type described and claimed in assignee's U.S. Pat. No. 6,853,093. Together with grid 246, grid 248 provides anti-tamper protection to the remainder of the flat cable and connector assembly 240. Preferably a layer 290 of epoxy is provided over doubled-over portion 270 within the enclosure 210, thereby providing a mechanically sealed, tamper-protected assembly.
Various types of suitable tamper detection and disabling circuits 280 are described in the following patent publications, the disclosures of which are hereby incorporated by reference: U.S. Pat. Nos. 5,998,858; 5,861,662 and 6,917,299.
